6^5.10^2/2^5.3^6.5
tìm soos nguyên x nếu biết
1/ 5.3\(^x\)= 5.3\(^4\)
2/ 9.5\(^x\)= 6.5\(^6\)+3.5\(^6\)
3 /2.3\(^{x+2}\)+ 4.3\(^{x+1}\)=10.3\(^6\)
Tìm số ự nhiên x biết.
a, 2x=46.163
b, 2x=\(\frac{47}{83}\)
c, \(\frac{2^{x-3}}{4^{10}}\)=83
d,5.3x=54
e, 9.5x=6.56+3.56

\(\frac{2^5.3^5+2^4.3^4}{2^4.3^6-2^5.3^5}\)
{x^2 -[6^2 -( 8^2- 9.7 ) ^3 -7.5 ]^3-5.3}?^3=1
3^(10)+6^(2)/5.3^(8)+20
3^(10)+6^(2)/5.3^(8)+20
Rút gọn:
\(\frac{2^5.3^6+6^5.11}{12^5-6^5.2^2}\)
\(\frac{3^{10}+6^2}{5.3^8+20}=?\)
